' 21 Claims.

My invention relates to apparatus tfor and method of forming pouch-like containers.

In this application I have illustrated and will describe theinvention in connection with a container of the type, which, so far as I am aware, prior to my invention was always produced by hand. Such a container includes a sheet of strawboard, cardboard, or the like, bent to form four walls of the container, the ends of which are closed by separate inserts. Around this structure there is applied a wrapper, and under the hand method of making these containers the production was slow and consequently costly.

In accordance with my present invention containers exactly of the type above described, and

presenting all of the appearance of those made by hand are produced by apparatus embodying an endless carrier for moving forming horns to several points or stations where, and between some of which, the steps for mechanically forming each pouch-like container are successively performed, with a plurality of pouch-like containers being continuously in process of manufacture.

The principal general object of the invention may therefore be said to reside in mechanically producing pouch-like containers of the above type including an end closure and four walls with a wrap-per therearound having all of the characteristics and general appearance of those previously made by hand. Such containers may be used for packaging tobacco or other materials, which have been sold for many years in a particular style or type of container known to the public, so that there will be no danger of loss of trade due to a change in appearance or structure of package. In this connection, I would mention the fact that even a slight change in the style or appearance of a known type of container or package, especially for tobacco and tobacco products, is likely to result in the loss of trade, for it is peculiar to many smokers and users of tobacco that they assume from a change in package that there has been a change in the quality of the merchandise. Such, of course, is not necessarily the case, but this peculiar attitude on the part of many persons necessitates, under present business methods and conditions, the mass production of containers formerly made by hand with a view to a reduction in cost without sacrificing the quality of the merchandise or changing the appearance of the package.

I will not dwell here in detail on the objects and advantages of the invention, as the same will be specifically pointed out during the course of the following detailed description of the apparatus shown in the accompanying drawings, but a general description of the invention should be helpful to a clear understanding of the views in the drawmgs.

What I have hereinbefore referred to. as form- 5 ing horns moved by an endless carrier include forms corresponding in external dimension and shape approximately to the internal dimension and shape of the completed pouch-like containers, and having suction ports opening on their 10 several faces with the ports on each face communicating with passages extending through the forth and communicating respectively at predetermined intervals with other passages leading to suction apparatus, so that when one of the forms arrives at station No. I, for instance, the end closure may beplac'ed against the end of the form and held thereto by suction. jThereafter this form is moved to station No. 2 carrying the end closure, while the succeeding form moves to station No. I. At station No. 2 the first mentioned form has fed thereto one of the straw board blanks in contact with one of its faces, and at the same time another end closure blank isbeing applied to the succeeding form at station No. I. While these operations have been taking place, the outside wrapper sheet is being fed through feeding mechanism from a continuous strip from which the wrapper to be applied to the blank on the first mentioned form has been cut to proper length, had adhesive applied thereto, and placed in position to properly register with the straw board blank carried by the first mentioned horn when it arrives at station No. 3. Upon arrival of the first mentioned form and blank carried. thereby at station No. 3, the wrapper and blank are brought into contact and adhesively united with the ends of the wrapper projecting beyond the edges of the blank and beyond the end closure on the form or horn. The wrapper, blank and end closure thus associated, are then carried through succeeding stations during which the blank and wrapper are folded around the horn and edges of the end closures, the blank being held held to the several faces of the horn by suction at each face in the manner previously described in connection with the end closure. Eventually the blank and wrapper are completely bent around the horn and form a tubular rectangular structure with the wrapper projecting beyond the ends 5. of the blank, after which the ends of the wrapper are partially folded in, pasted and then completely folded against the said end closure. After completion of the pouch-like container in the foregoing manner on the first mentioned horn, 5

the suction is all released and eventually the container with one end open for filling is blown from the form or horn and conveyed away for filling. The first mentioned form which carried the container and from which the container was blown or removed then returns to station No. I and the foregoing operations are repeated, it being understood that each successive horn or form held by the endless conveyor moves successively through the same steps described in connection v with the first mentioned horn and that the operation is continuous, there being several pouch-like containers continuously in process of formation at the same time.

Fig. 39 is a top plan view of the endless conveyor, forming horns, and showing the formation of the container thereon in proximity and association with Figs. 28-38 respectively.

In Figs. 1 and 2 of the drawings, the several stations at which the steps in the formation of the container are performed are numbered respectively I, 2, 3, 4, 5, 6, I and 8, the same being located at spaced intervals around and on the frame 9 within which is rotatably mounted the turret I0. As shown in Fig. 12, the turret I0 includes a top or table II to which are fixedly secured at regular spaced intervals, the forms or horns I2 on which the containers are produced. The table II is fixedly secured to the shaft I3, which is rotated by Geneva gear mechanism indicated generally at I4 and driven by a disc I4 on shaft I5 which is connected to a pulley I6 (Fig. 2) which is rotated by belts H from any suitable source of power, not shown.

Referring back to Fig. 12, it will be noted that the table II rests on a support I8 having depending bosses I9 which receive dowel pins 20 which also extend into fixed frame 9 through which the shaft I3 extends. Coil springs 22 surround the rods 20 and abut the top of the frame 2I and the bottom of the bosses I9 to yieldably urge the plate I8 into engagement with the table II. The plate I8 is fixed and not rotatable, and as shown best in Figs. 3, 6, 12 and 39 has formed in its upper face an arcuate groove 23 extending from in front of station No. I to the front of station No. 5. As shown best in Fig. 39, the groove 23 between stations Nos. I and 2 is relatively narrow but becomes wider between stations Nos. 2 and 3 and wider still between stations Nos. 3 and 4, and then between stations Nos. 4 and 5 abruptly terminates into another narrow end similar to that between stations Nos. I and 2. Referring again to Fig. 12, a pipe 24 leads to suction apparatus, not shown, and communicates with the passage 23. Referring to Fig. 6 where one of the forming horns is shown in detail as comprising a rectangular block having at one end lateral extensions 25 through which screws 26 are mounted, the screws extending into the table II to rigidly secure the ,horn to the table for rotation therewith. The

horn [2 extends radially outward from the table II. At its outer end portion and on each of its faces, each of the horns I2 is provided with ports or openings 21 which communicate with longitudinal passages 28 in the horn. There are also portsZl in the outer end of the horn communicating-with passages leading longitudinally through the horn. Above the table II the passages 28 communicate with ports 29 which are arranged to successively register with the different portions of the groove 23 as the table II rotates. For instance, the passages 28 communicating with the ports in the end of the horn I2 at station No. I are established in communication with the narrow end of the groove 23 and at station. No. 2 the ports on the bottom face of the horn and their passages will be established in com munication with the channel 23 at station No. 2, and so on, as hereinafter more completely explained. As shown in Fig. 12, there are passages 30 through the table corresponding tothe passages 29 and in registry therewith and through which communication with groove 23 is established.

Before proceeding with the detailed description of the construction and operation of the apparatus for performing the steps in making the container, that is, the mechanism at each of the stations, I would have it clearly understood that as the shaft I3 is driven by the Geneva gear mechanism I4, that the table I I and forming horns I2 mounted thereon at regular intervals rotate so that each of the horns stops at and passes successively each of the stations. The number of horns corresponds to the number of stations.

With the foregoing in mind and referring to Figs. 3-5 which specifically relate to station No. I, the numeral '3I designates a support in the nature of a bracket rigidly connected to the frame 9, extending outwardly from one side thereof. The bracket 3I is formed at its top with a horizontal portion, the top of which is substantially in alinement with the top of the table II. On this horizontal portion of the bracket 3I and above its top there is mounted a magazine 32 in which are stacked the end closures for the containers in the nature of cardboard or strawboard pieces 33 which feed down to the bottom of the magazine by gravitation. The front and back walls of the magazine terminate above a plate 34 a distance equal to the thickness of the end closures 33, so that the lowermost end piece may be pushed from beneath the stack in the manner hereinafter described. The front edge of the plate 34 is located substantially in alinement with the front lower edge of the magazine, and immediately in front of the plate 34 and therebelow is a hinge bracket 35 which is between the arms 35 of a pusher 3'1! pivotally mounted on pin 38 through the arms 35 and stop 35. Face 3'! of the pusher 37 will be positioned by the stop 35 in alinement with the plate 34 to receive one of the end pieces when pusher 31 is oscillated on the pivot 38 from the position of Fig. 3 to that of Fig. 4. The mechanism which feeds the lowermost end closure from the magazine on to the face 31', comprises'a slide 43 substantially of the same thickness as the end pieces 33 and normally located back of the magazine 32 in the position shown in Fig. 3, resting on the top of the bracket 3I. The slide 40 has depending lugs 4i through which, and a slot 42 in the upper end of the bell crank lever 43, is mounted a pin. The

bell crank lever is pivotally connected on the bracket at 45, and its lower arm is pivotally connected at 46 to the rod 4"! connected to the crank mechanism designated generally by numeral 48 and journaled on the shaft 49 mounted through depending portions 50 of the bracket 3I. The shaft 49 is keyed to a sprocket wheel 5I over which is trained the chain 52 leading to driving mechanism hereinafter described for rotating the shaft 49 and actuating the crank mechanism 48 and bell crank lever 43, whereby the slide 45 is reciprocated from the position shown in Fig. 3 to the position shown in Fig. 4.

The pusher 3'5 is actuated also by the movements of the slide 40. To accomplish this, the arms 35 are pivotally connected at 53 to the ends of rods 54-, the other end of which extend through an opening in a depending bracket 55 at the end of the slide 43. The bracket 55 is provided with an extension 56, the front end of which confronts a similar member 51 which extends from a cross piece 58 between the rods 54. When the slide is in its outermost position, which is that shown in Fig. 3, av depending lug or pin 59 on the slide 40 is in contact with the cross piece 58. When the crank mechanism 48 is actuated to oscillate the bell crank 43 to carry its upper end toward the magazine 32 from the position shown in Fig. 3, the slide 48 is also moved toward the magazine and initially the part 56 engages the member 51 moving the rod 54 to the left and thus oscillating the pusher 3l on its pivot 38 to place it in the position of Fig. 4. After this has taken place, the part 56 rides past the abutment 51 so that the slide 43 continues to move through the magazine 32 and push the lowermost end closure 33 on to the face 31 of the pusher 3? as shown in Fig. 4. During this movement, the forming horn has been approaching station No. I and when the forming horn reaches station No. I the Geneva gear mechanism stops the table and horn while the crank mechanism 48 returns the slide 40 from the position of Fig. 4 to the position of Fig. 3, during which the part 56 rides off of the abutment 51 and the lug 59 approaches the cross piece 58. When the lug 59 engages the cross piece 58 it exerts a pull on the rods 54 and oscillates the pusher 3'! to place the end piece 33 which has been fed thereon against the end of the horn. Now, when the horn reached station No. I, as previously mentioned, the passages 28 leading from the end ports 21 to the ports 29 have placed the end ports in communication with the channel 23 and hence in communication with the suction apparatus, so that when the pusher 31 places the end piece 33 against the end of the horn at station No. I, the suction is on at the end ports and the end piece is held on the horn thereby. The horn then moves to station No. 2 to receive the main body blank or strawboard liner.

The construction and arrangement of the parts comprising station No. 2 are shown in detail in Figs. L10, wherein the numeral 6I designates a bracket also rigidly secured to the frame 9 and supporting a top plate or table 52 above which is mounted the magazine 63 in which are arranged the blanks or liners 34 (shown in detail in Fig. 29) in the nature of rectangular pieces of cardboard scored along lines a to provide panels b, c, d, e and f, of which panels 0 and 6 form the front and back, and panels b, d and ,f, the sides of the completed carton, with the panels 1 and I) overlapping. Referring again to Figs. 710, the plate 32 is provided with slots 52' receiving rack bars 65 movable along the slots beneath. the magazine 63. To the tops of the rack bars 65 there is connected a pusher plate 6'! movable across the table 62 beneath the magazine 63, running in the guide ways 66, and of a thickness corresponding substantially to that of the blanks 64, whereby it may push a blank forwardly from beneath the magazine 63 to mechanism hereinafter described for feeding the blanks to the forming horns. Toothed segments 68 are in mesh with the teeth on the rack bars 65, and are connected by arms 69 to hubs I journaled on a shaft I! supported by opposite side plates of the bracket 6I A lever I2 is pivotally connected at I3 to a link I4, said link being connected to a crank disc I by means of the crank pin I6. Crank disc I5 is fixed to shaft I8 which is driven by a sprocket I9 and chain 89, which is also (see Fig. 2) trained over a sprocket 8| on a shaft 82 driven by suitable gears from the shaft I5. The rotation of the crank wheel I5 will impart to the link I4, a reciprocating motion to rock the lever I2 and oscillate the segments 68 since lever 'I2is connected to shaft II, whereby the rack bars 65 will be reciprocated to move the pusher 61 back and forth under the magazine 63. Obviously, each time the pusher 61 moves forwardly or to the left of the position shown in Fig. '7 to the position shown in Fig. 8, one of the blanks 64 will be pushed forwardly until it has passed under latches 83 having hooked ends 94 disposed immediately in front of the magazine 63. The latches are pivotally connected at 85 to supporting arms 86 mounted on a support 81 above the table 62. Forward movement of each member 64 brings its front edge initially into contact with the beveled face of the hooked end 64, whereby the latches are raised so that the blank may pass thereunder and when the member 6'I reaches the limit of its forward movement, the rear edge of the blank is engaged by the shoulder of the hooked end 84. Rods 88 are also mounted in the slots 62' for reciprocating movement by the racks 65 simultaneously with the pusher 67. Dogs 89 are pivotally mounted at 99 to the rods 88 and springs 9I normally hold the front ends of the dogs above the tops of the rods 88. At the time that the pusher 61 is in the position of Fig. 7, the front ends of the dogs 89 are substantially in alinement with or slightly behind the hooked ends 84 of the latches 83 and just behind the rear edge of the blank 64 beneath the latches, so that forward movement of the rack 65 will move the blank 64 from beneath the latches 83, due to engagement of the dogs 89 with the rear edge of the blank, whereby the blank will be positioned beneath the horn which has moved to station No. 2 with the end closure 32 on its end. In starting a blank 64 is placed under latches 83.

The relative position of the end closure and blank 64 after the dogs 89 have moved the blank 64 beneath the horn is shown in Fig. 29, wherein the end closure 32 is perpendicular to the panel 0 with its ends in alinement with the creases a at opposite sides of the panel 0. In Fig. 29, it will also be noted that the panel I is bent upwardly. This is accomplished at station No. 2 by the member 92 which has one arm 93 connected to a pinion 94 and its other arm 95 extending toward and into an opening 96 in the top 62. The member 92 is located in alinement with the latches 83 and hence in alinement with the blank thereunder. Now, when the blank 64 is delivered beneath the latches 83, the panel 1 is disposed above the opening 96. The shaft 91 on which the pinion 94 and member 92 are mounted is journaled through and supported by brackets 98 on the bracket 6I. A rack bar 99 has its teeth in mesh with the pinion 94 and is slidable in a frame I00 on the bracket 6|. A stud or roller I OI projects outwardly from the frame I00 through slot I62 and is disposed against the cam disc I93 operated by and keyed to the shaft TI. The member 92 is normally held in the down or full line of Fig. by a spring I64 connected at its top to the member 92 and at its bottom to a stud or screw I95 on the bracket 6|. When the shaft H is rotated by the crank I5 and link I4, the projection on the cam disc I93 engages the stud or roller I III lifting the same and hence raising the rack bar 99 and rotating the pinion 94 and also member 92 to the dotted line position of Fig. 9, so that the panel which is disposed above the end of the member 92 and opening 96 is bent up to the dotted line position of Figs. 9 and 10 and the full line position of Fig. 29. To hold blank 64 down while finger 92 is turning flap 1 to the angular position, flat spring members 81 are provided which are mounted on support 81. These also tend to guide the blank or rather hold it down so that pushers 89 will not ride under the blank.

When the horn I2 arrived at station No. 2 it was in alinement with the panel 0 on the blank 64 and thus ports 29 which communicate with ports 21 in the lower face of the horn were disposed over the wider portion of the channel 23, and therefore in communication with the suction apparatus so that when the blank 64 is pushed under the forming horn, as shown in Fig. 29, it is held to the horn by the suction through ports 2'! in the bottom face of the horn. The horn is then ready to move to station No. 3 with the end closure 33 held to the end of the horn, the panel c below the horn and below the end closure 33.

While the foregoing operations were taking place, the outside wrapper was being prepared and position at station No. 3 for proper association with the blank 64 in the condition and position in which it left station No. 2.

The construction and arrangement of the parts constituting the mechanism of station No. 3 is shown best in Figs. 1, 11 and 12. Referring to Figs. 1 and 11, the numeral I66 designates uprights on which are brackets IU'I provided with trunnions I98 rotatably supporting a shaft I69 on which is a drum I I9 containing a'roll of paper of predetermined width. The uprights I06 also rotatably support a shaft III to which is keyed a sprocket wheel II2 continuously rotated by a sprocket chain I I3 and sprocket wheel I I4 driven by a stub shaft II5 (Fig. 11) on which there is a sprocket wheel II6 over which, and a sprocket wheel III on shaft H9, is trained a chain H8. The shaft H9 is driven by a gear I29 (Figs. 2 and 12) meshing with the gear I2I on shaft I5.

Referring again to Figs. 1 and 11, particularly the latter, there is shown also keyed to the shaft III a roller I22. Another roller I23 is mounted on the shaft I24 above the roller I22 and between the uprights I96. The shaft I24 is journaled in blocks I25 normally urged by springs I26 downwardly or toward the roller II 2. The springs are mounted around stems I 21 connected to the blocks I25 and to cam discs I28 on the shaft I29 which may be turned by the handle I39, whereby the shaft I 24 may be raised or lowered with respect to the shaft III to raise and lower the roller I23 with respect to the roller I22. The paper from the drum IIIJ runs first roller I35 on a shaft I36 adjustably mounted between the uprights I34 through slots I31 and held in desired-position by nuts I38.- The paper then comes down and under another roller I32 journaled on the frame I33 in alinement with the roller I32, and over a roller-I39 journaled between brackets I49 on uprights I4I and then across the plate I42 on uprights I M, and between rollers I43 and I44, across'the plate I45 on uprights HM and plate I46 and between rollers I41 and I48, across plate I49 to the adhesive applying'and wrapper positioning apparatus hereinafter described. Rollers I43 and I44 are geared together by gears I43 and I44. The roller I44 is journaled on the shaft I58 between uprights I4I and a gear wheel I5I is keyed to the shaft I58. Also, between uprights I4! and below the shaft I59 is a shaft I52 to, which is keyed a Geneva gear I53 and'a gear I54 meshing with the gear I5I. Adjacent sprocke et wheel H4 is a Geneva driving disc I56 which carries a lug I56 engaging between the teeth on the Geneva gear to impart to the same a quarter turn each time the wheel I56 makes a complete revolution, whereby the gears I54 and I5I and rollers I43 and I44 are rotated a pre determined amount. The roller I43 is mounted on a shaft I5'I in an adjustable mounting indicated generally by the numeral I58 and identical to the mounting for the shaft I24 "previously described. Inasmuch as the roller I43 is constantly urged toward the roller I44 and driven therefrom the paper is gripped th'erebe} tween so that each time the rollers I43 and I44 turn a predetermined amount the paper will be fed across the plates I45 and I46 a predetermined distance. At this point, I would explain that the paper from the drum I I8 is constantly pulled by the rollers I22, I23, whereas the paper between the rollers I43- and I44 is intermittently pulled. It is for this reason that I provide the compensating arrangement of the rollers I32, I32 on the slidable frame I33, as each time the rollers I43, I44 pulls the paper the frame will slide up, and each time that the rollers 143,.

I44 are idle the frame I33 will slide down, so that the paper will always be under proper tension. To facilitate this operation, cables or ropes I59 are attached to opposite sides of the framejI3-3 and run over pulleys I88 journaled at I6! on the uprights I34. To the other end of the rope there is attached a weightI62 compensating' for the weight of the frame I33 and rollers I32. r

In order to cut the-web of paper into predetermined lengths and form the wrappers, I provide intermediate the plates I45 and I46, a pair of cutting blades. One of the blades I63, is pivotally mounted on a stub shaft I63 journaled in the trunnion I54 supported by plate I86 on uprights I85. Theouter end of the blade I63 has a projection I 65 received in the end of a link I66. 1 The other bladeI61 is fixedly secured to the support I64 beneath the paper. The other end of the link I66 is pivotally connectedat I68 to a lever I69 carrying a projection Ililand pivoted at its other end at 'I1I to the frame or uprights I4I. On the shaft II5,,there is a cam wheel II2 having a formation to engage the projection I19 each time wheel I12 rotates to thereby oscillate lever I69, link I66end the blade I63 se -that the paper will be severed between the blades I63 and I61 and plates I45 and l46. That portion of the paper on the plate I46 is of predetermined length and is disposed between the rollers I41 and I48, the former'being mounted on a shaft I13 carried by a mounting similar to the mounting I58 and I23with:a.spring urging it down, so that the roller I41 yieldably contacts roller I48, wherebythe paper is tightly gripped between the rollers. Shaft I13 is keyed to a gear I41 and the roller;l48 isgon the shaft I14 (Fig. 11) mounted between the sides of the frame and is keyed to a sprocket wheel I15 over which is trained the chain I16. A sprocket wheel I11 is keyed on the shaft H9. The'chain I16-is also trained around the sprocket wheel. I11. Shaft I14 is also keyed to'a gear meshing with I41. Thus, the rollers I4 I49, are rotated by the gears and sprockets IIl, I15, and chain I16, so that the cut lengths of paper will be fed across plate I49 to the adhesive applying mechanism.

Uprights I85 support a plate I86 on which are mounted the cutting knife and frame I86 for the rollers I41, I48. This latter frame has secured theretoabracket I81 supporting the adhesive applyingframe I88 in which is located a glue container I89. 'The bottom of the container I89 is open and at one side thereof there is a flexible strip I96 contacting roller I9I, which is mountedbelow the open bottom of the container I89, on ashaft I92 to which is keyed a gear I93 (see Fig. 12). The table I86 also supportsan electric motor I94 which drives gear I95 meshing'with the gear I93, whereby the roller HE is rotated in a contra-clockwise direction. Rollers I96 and I96 are mounted beneath the roller I9I incontact therewith and substantially in alinement with the plate I49. On the side of the roller I9I-,opposite to the plate I49, is a rod I91 supporting fingers I98 having pointed ends disposed between rollers I96 and I9I. The piece of paper between rollers I46, I48, which was severed by the cutting blades I 63, I61, is fed between rollers I9I and,I96.- Since the surface of the roller I9I is coated with the adhesive from containerl89, the paper will be-coated with adhesive on one face and fed between rollers I96 and; I9I.- The pointed ends of the fingers I98 prevent the paper from rotating with the roller I9I past the ,;roller I96" and consequently the paper is deposited in a position on the turret indicated generally by the numeral I99, such position being determined by the stop or guide 290. This piece of paper is the wrapper to be applied to the blanks carried by the forming horn and the upper face of the wrapper is that which is coated with the adhesive.

The wrapper is held in the predetermined position on the turret by the frame 268 and vacuum through .suction portions 26I and channel 202 in the turret, and connection to suction apparatus hereinafter referred to. The wrapper is relatively thin andlight, and I have found that the suction ismoreeifectiveif the paper is forced down against the turret above the ports 29L To this end, I provide a pipe 293 connected by valve 204 to a pipe 265 leading from a source of compressed air. The valve 284 has projecting therefromastem 286 normally heldin the position shown in Fig. 11 by any suitable means, such'as a spring within the valvecasing. At any suitable point, such as station No. I, I mount the valve 244 on the main frame. A lever 201 is pivoted on the bracket 3| supported by frame 9.

Beneath the lever 291 is a cam disc 299 keyed to the shaft 49 which is driven by sprocket 5I and chain 52 running over sprocket wheel 2I3 keyed to shaft II9. Hence, ever; time the shaft H9 makes a revolution the cam wheel 299 is rotated so that the projection on the wheel 299 will rock the lever 291 and open the valve 294, whereby a blast of air is projected through pipe 293 on to the wrapper which has been delivered on to the turret I99, so that when suction is applied through ports 29I, the wrapper will be pressed against the turret and firmly gripped against the turret by the suction through ports 29I.

The table or turret I99 is provided with diametrically opposite openings 2I4, 2I4 (see Fig. 12), and these openings are brought below and within the wrapper guiding frame 299 (see Fig. 1), and surrounded by ports 29I. One of the openings 2| 4 or 2I4 is disposed in front of the wrapper sheet delivery mechanism at the time a wrapper is being fed outwardly on to the turret above the opening. At such time the forming horn, which has moved from station No. 2 is disposed over the other opening for application of the wrapper to the blank carried by the forming horn in the manner presently described. While a wrapper is being applied to the forming horn at station No. 3, a blank is being applied to the succeeding forming horn at station No. 2, and another wrapper is being prepared and delivered on to the turret. Hence, when the succeeding forming horn moves to station No. 3, the wrapper which is being delivered is-moving to position for association with the blank on the said succeeding forming horn which is moving from station No. 2.

Referring now to Figs. 12-14, wherein the wrapper applying mechanism is best illustrated, it will be noted that the turret or table I99 is mounted on a shaft 2 I5. On the said shaft and above the turret is a cap 2I6 engaging a washer or plate 2I1. The cap 2I6 is substantially cupshaped to provide the suction passage 292 previously mentioned. The top of the shaft also has secured thereto a washer or abutment 2I8 which may be held rigidly in place by a nut 2| 9, sothat a coil spring 220 is compressed between the abutment 2 I8 and the end of the cap 2I6 to urge the cap down against the plate 2H and maintain it in proper position.

Referring momentarily to Fig. 1, it will be noted that a conduit 22I leads into the cap 2 I6 in communication with the chamber or passage 292. This conduit may be connected to suction apparatus not shown.

Secured to the upper end of the cap 2I6, is a tubular member 222 having a lateral projection 223 rigidly supporting a pin 224 which is connected to a rod 225 fixedly secured to any fixed part of the frame such as a bracket 226, whereby the member 222 and cap 2I6 are held against rotation. Beneath the turret and around the shaft 2 I5 are interfitting plates 221 and 228, the turret resting on the former, and the latter having a boss 229 through which the shaft 2I5 extends. Below the boss 229 and keyed to the shaft 215 is sprocket wheel 239 around which is trained the sprocket chain 23I, also trained. around the sprocket wheel 232 on and driven by the main shaft I3 of the table I I. The ratio of the sprocket wheels 239 and 232 is such that every time the table II makes a one-eighth revolution the turret I99 makes a one-half revolution. The lower end of the shaft 2I5 is supported in a journal 233, which as shown in Figs. 11 and 12,

is supported by levers 234 connected to the journal by pivot pin 235. One end of the lever 234 is pivotally connected at 236 to a bracket 231 which is rigidly connected to an elongated boss 238 connected to the frame by webs 239. The other end of the lever 234 is pivotally connected at 249 to a crank arm 24I connected at its lower end to a crank shaft 245, one end of which is keyed to a sprocket wheel 246, over which and a sprocket wheel 241 on shaft H9 is trained the chain 248. Obviously, the sprocket wheel 241 is driven by the shaft H9 previously described. Under the foregoing arrangement, the turret is intermittently rotated and raised and lowered as later pointed out in detail.

Referring to Fig. 12, a plate 249 is rigidly connected to the top of a rod 259, which is pivotally connected by the pin 25I to crank rod 252, which is driven by cam wheel 253, also keyed to the shaft 245. Inasmuch as the plate 249 is normally disposed in and substantially closing the opening 2I4 in the turret when the paper wrapper is being delivered, and inasmuch as the turret must rotate to deliver the wrapper at a diametrically opposite position from that shown in Fig. 12, the plate 249 must be removed from the opening during such rotation of the turret. This is accomplished by the crank 252, the operation of which is such as to lower the plate 249 during rotation of the turret and to raise the plate 249 to the position shown in Fig. 12 when the turret is stationary.

When the turret is rotated to bring the opening 2I4 and the Wrapper disposed thereabove into the position of the opening 2I4 of Fig. 12, the forming horn has brought the blank in the condition illustrated in Figs. 29 and 30 over the turret as shown in Fig. 12. The relative positions of the blank and wrapper at such time are as shown in Fig. 30. The crank shaft 245 then raises crank arm MI and lever 234, so that the journal 233, shaft 2I5 and turret are raised until the pasted face of the wrapper contacts the blank on the forming horn. To firmly hold the wrapper and blank in proper relative position at station No. 3 during operations about to be described, I provide a pad 255 in a plate 256 supported by a shaft 251 which is mounted in sleeve 258 supported by a boss 259 on the frame. The lower end of the shaft 251 is hollowed as indicated at 269 to receive a coil spring 26I which is also within the sleeve 258 and the lower end of which rests on the end 262 of a coupling 262. The coupling 262 is pivotally connected at 263 to the upper end of link 264. The end 26I is reduced and is within the sleeve 258, and the portion of the member 262 around the reduced end 26I is in engagement with the sleeve 258. As shown in Figs. 12 and 13, a pin 265 is mounted through sleeve 258 and slot 266 in the bar 251. The link 264 is connected at 268 to a crank disc 219 driven by the shaft 245. When the link 264 is lowered by operation of the crank, the plate 256 and pad 255 will be withdrawn from the opening 2I4 or 2I4, whichever happens to be in the position shown in Fig. 12, in the same manner that the plate 249 is lowered and at the same time which is during rotation of the turret. When the turret stops with say the opening 2I4 in the position shown in Fig. 12, and the wrapper beneath the forming horn, the crank raises the link 264, whereby the sleeve 258 and rod 251 also are raised, which movement occurs after the turret has come to rest and has been raised to bring the wrapper into contact with the blank on the forming horn as shown in Figs. 13 and 14. The pad 255 is then pressing against the wrapper beneath the panel 0 on the blank, and due to the slot 256 and pin 265 the pressure against the forming horn may be relieved, as the rod 251 can yield down against the spring 26! with the slot moving relatively to the pin 265.

It will be noted in Figs. 13' and 14, that the pad 255 does not fill the entire opening in the turret, but, as stated, contacts the wrapper beneath the panel 0, so that the panels d and e lie in the plane with panel 0 with the panel d above a roller 212 supported in a bracket 213 on a rod 214, the lower end of which (see Fig. 11) is pivotally connected at 215 to one end of the lever 216, the other end of which is pivotally supported at 211 on a fixed support 218. Intermediate its ends the .lever 216 has connected thereto a lug or roller 219, which is disposed in a cam slot 280 in wheel 281 keyed to and driven by shaft H9. The formation of the cam slot 280 is such that the lever 216 will be oscillated at proper intervals to reciprocate the rod 21%, whereby on upward movement of the rod the roller 2'12 will pass against the panel 1% and portion of the wrapper thereover bending the panels (2 and e from the dotted line position of Fig. 14 to the full line position, at which time the suction will be on at those ports in the side of the forming horn on the face against which the panel (I is disposed. The rod 2M is then drawn downwardly to a position below the turret and out of the opening 214, as is plate 2&9 and pad 55, so that the turret may rotate one-half revolution to receive a new wrapper and bring another be neath the next horn.

Inasmuch the panel Q will be folded down against the upper face of the forming horn with the panel I against the side of the forming horn opposite the panel 03, to be held in place by suction through ports on the top'and other side of the horn, and the panel 2) is tobe bent up against the panel I preferably apply at station No. 3 a spot of glue 282 on panel b, so that it will be held firmly to the panel f, while the formation of ti e pouch is being completed (see Figs. 30-33).

. The means for accomplishing this is shown best in Figs. 12 and 1, wherein the numeral 283 designates generally a glue spotter in the nature of a container supported in a frame 284 on a lever 285 pivotally connected at 2% to a support 231 above the turret ii. At the side of the turret ll opposite station No. 5, the lever 285 is provided with a lug 285 disposed in the forked end 288 of crank 239, which carries a lug or roller 2% disposed in cam slot till of a drum 282 on shaft 293, which driven by mechanism hereinafter described in connection wi'thstation No. l. Obviously, when the crank 239 oscillates, it will rock the lever 285 on its pivot 236 to raise and lower the spotter 283 to apply the spot of glue 282 to the panel 1).

After the foregoing steps have been performed at station No. 3, and the parts 269, 255 and 212 have been lowered out of the openings 2M, 25 1, the turret begins its one-half revolution and the forming horn with the blank and wrapper in the position shown in Fig. 31 begins to move to station No. 4. During movement of the said forming horn between stations Nos. 3 and t, the panel c is bent down against the top of the forming horn by mechanism shown in Figs. 15, 16, com prising a roller 2% mounted on a pin 296 in bracket 291- on rod 298. The bracket and roller 295 are supported by the rod at a predetermined distance above the forming horn, such that the roller will contact the Wrapper and panel 6 and press the same down against the forming horn as shown in Fig. 15, wherein the arrows indicate the bracket and roller 295 moving to the right and the forming horn and blank moving to the left. When the panel e is folded down against the top of the forming horn, suction is on the ports in the top of the forming horn and also in the ports on the right side of the forming horn, in respect to the position shown in Fig. 15, so that panels e and 1 will be held against the forming horn by suction. The blank is then substantially encircling the forming horn with the exception of panel 19 and one end of the wrapper.

Referring to Fig. 1, it will be noted that an arcuate track 299 is provided above the turret, and the rod 298 has a guide 3! engaging the track. One end of the rod 2% is connected at 38! to one end, 32, of a bell crank lever pivotally mounted on upright and the other end 30d of the bell crank lever is connected at 305 to a coupling 386 which carries a rod till, one end of which extends into a tubular housing 308. The other end or the housing 358 receives a rod 389 carried by a coupling 3H1 connected at 3H to one end of a lever 352, the other end of which is connected at 383 to a link 3M, said link 3! being connected at 325 to crank 355 and which as shown best in Fig. 12 is driven by the shaft i 5. The lever M2 is pivoted intermediate its ends at 3i? on a fixed support 358. Obviously, the crank 353, through the link 31%, will impart an oscillating movement to the lever 3E2, whereby the rod 3% is moved back and forth in the housing 338 and against the spring 319 between the rods 339 and till, so that the spring will push the rod 3%? and oscillate the end 35! of the bell crank lever to swing the rod 298 back and forth across the path of movement of the forming horn, as shown in Fig. 1. Referring again to Figs. 15 and 16, it will be noted that the rod is moving oppositely to the direction of movement of the forming horn between stations Nos. 3 and 4, so that the panel e is contacted by the roller and folded down against the top of the horn in the manner previously described.

The mechanism of station No. 4 and the operation which takes place after the forming horn arrives at station No. i is shown best in Figs. 16 and 17, wherein the numeral 329 designates a plate supported horizontally at the upper end of a rod 32! which slides in fixed plates 322, and the rod 321 has secured thereto ears 323 between which is pivoted a coupling 32% which is connected to a rod 325 extending into a sleeve 326 and contacting a coil spring 321. Another rod 328 extends into the other end of the sleeve 326 and contacts the other end of the spring 321, and is secured to a coupling 32%! connected to a crank 330. The crank 33!} is keyed to a shaft 33! which (see Fig. 2) is also keyed to a sprocket wheel 332 over which, and a sprocket wheel is trained a chain 334. The sprocket wheel 333 is on the shaft 32 driven by a gear 336. Referring again to Fig. 17, it will be noted that the plate 328 is in its uppermost position to which it has been raised by the crank and link mechanism associated therewith. On the plate 320' there is an upstanding angle piece 3M having its upper end offset. The angle piece 3&0 is in such position, relative to the point where the forming horn stops at station No. 4, that it will engage, as shown in Fig. 16, the flap b and free end of the wrapper and fold the same up against the flap f. It will be remembered that the glue spot on the flap f is there for the purpose of securing flaps b and together. During this operation the rod 298 carrying roller 295 has been returning toward station No. 4 as indicated in Fig. 16, and, as shown in Fig. 17, will engage the upstanding end of the wrapper and press the same down against the top flap of the wrapper and panel e, after which the forming horn moves from station No. 4, to the left of the position shown in Fig. 17, whereby the wrapper passes under a holddown plate 34! which will prevent the pasted top flap of the Wrapper from coming free. When the said forming horn moves from station No. 4 toward station No. the next one is moving from station No. 3 to station No. 4, and the roller 295 will contact the upstanding blank and wrapper on said last forming horn and then return and contact the wrapper at station No. 4 after the plate 349 has folded the wrapper upward. Fig. 34 shows the condition of the blank and Wrapper as it passes beneath the plate 329 to station No. 5 where the ends of the wrapper are partially folded to the position shown in Fig. 35.

The mechanism of station No. 5 is shown generally in Fig. 1 and more in detail in Figs. 18 to 21 inclusive, and wherein bracket 342 supports uprights 343 through which rods 344 are slidably mounted. The outer ends of the rods 344 are connected by a cross piece 345 through which is mounted a set screw 346 by which the amount of sliding movement of the rods 344 toward the forming horn may be regulated, the set screw acting as a stop when it abuts the outermost upright 343. A strap 341 is fixedly connected to both of the rods 344, and is provided intermediate the rods with a pin 348 disposed in a slot 349 in one arm 359 of a bell crank lever, which is journaled on a shaft 35I. The other arm 352 of the bell crank is pivotally connected at 353 to one end of a link 354, the other end of which is connected to a pin 355 on a wheel 356 keyed to and driven by a shaft 351, which is connected to a sprocket wheel 358 (Fig. 21). The sprocket chain 359 which is trained over the wheel 358 is also trained over sprocket wheel 369 on the shaft H9 (Figs. 2 and 12). Returning to Figs. 1 and 18-21, the end of the rods 344 have connected thereto a yoke 36 I, in the ends of Which are journaled rock shafts 362, each carrying folders 363. Referring in detail to Fig. 22, it will be noted that the folder 363 comprises a central portion 364 of substantially the same width as the sides of the container. At each end of the central portions 394 are flaring wings 365. Meshing gear wheels 366, Figs. 18 and 21, are connected to corresponding ends of each of the cranks 362 and one of the gear wheels has a pin or roller 361. Fixedly secured to the uprights 343 is a bar or rod 368 having its end nearest the forming horn bent as indicated at 369. Also slidably mounted through the uprights 343 is a rod 319 carrying the projection or lug 31I. The rod 319 is connected to one end of the bell crank lever 312, the other end of which is connected to a link 313 driven by cam 314 working on cam roll 315.

As the forming horn is approaching station No. 5, the rods 344 and parts associated therewith and carried thereby are in the dotted line position of Fig. 19, and the lug 31I is in its innermost position. Upon arrival of the forming horn at station No. 5, the Geneva gear mechanism driving the turret I I stops the forming horn in the position shown in Fig. 19, whereupon the crank 356 operates to bring the yoke 36I toward the forming horn and positioning the folders 363 alongside of the ends of the wrappers to the position shown in Fig. 22. Following this operation cam 314 retracts the rod 319 and projection 311 which engages with the roller 361 on one of the gears 366 causes the cranks 362 to turn the folders 363 against the sides of the wrapper to the position shown in full lines in Figs. 19 and 21 or from the full line position of Fig. 20 to the dotted line position, whereby the end of the Wrapper is partially folded as shown in Fig. 35. After the ends have been so folded, the rods 344 are retracted by the lever 359 and the roller 361 will contact the end 369 of rod 368 and be returned to the dotted line position of Fig. 18, whereby the cranks and folders are returned to the position of Fig. 22. The rod 319 is also moved inwardly to be in position for the next pouch as it comes from station No. 4.

The next step is to apply adhesive to the partially folded ends of the wrapper preferably in the manner shown in Fig. 36, that is, with spots of adhesive on the wrapper and end closure and on one of the flaps of the wrapper. This is done at station No. 6 to which the forming horn moves from station No. 5. Reference should be had to Figs. 1, 23-25 for a clear understanding of the description of station No. 6. A tank 389 containing liquid adhesive such as glue is supported on a bracket 38 I, and a shaft 382 is journaled through opposite sides of the tank and is coupled at one end 383, to a stub shaft 384 journaled in the trunnion 385 on a support on the bracket 38I. A gear 386 on shaft 382 meshes with a gear 381 keyed to shaft 388. A sprocket wheel 399 is also keyed to the shaft 388 and is driven by a sprocket chain 39! trained around the sprocket wheel 392 on shaft 389. Shaft 389 also has keyed thereto a sprocket 399' and is driven by chain 39 I trained over the sprocket 392', (see also Fig. 2). A segmental plate 393 is keyed to the shaft 382 for rotation therewith so that the plate 393 will be dipped into the glue each time the shaft 382 makes a complete revolution. Uprights 394 extend above the tank and rotatably support the shaft 395 which carries a plate 396 on one face of which confronting the segmental plate 393 are projections 391, the ends of which are adapted for contact with the surface of the plate 393 to receive adhesive therefrom. The plate 396 is supported or positioned immediately in front of the point at which the forming horn stops andbehind the uprights 394 are plates 398 and 399 spaced apart a distance sufficient to permit the forming horn with the wrapper and strawboard liner or blank to pass therebetween with the partially folded ends of the wrapper on the sides of the plate confronting the member 396. The plate 396 also has a projection 499 above the projections 391 and above the segmental plate, so that the small plate 49I on the end of the projection 499 will not be contacted by the plate 393 and therefore will not have adhesive applied thereto. The shaft 395 is oscillated to swing the plate 393 from the position of Fig. 23 to the position of Fig. 25 by a lever 492 connected to the shaft and receiving the end 493 of rod 494 having a projection 495 riding against the surface of the cam wheel 496 on the shaft 389. The end of the rod 494 is provided with a slot 491 through which the shaft 335 extends. The relative movements of the plate 396 and plate 393 is such that the segmental plate wipes across the faces of the projections 39'! when the plate 396 is positioned as shown in Fig. 23 and after the segmental plate has passed across the projections, one of the forming horns has positioned the partially folded ends of the wrapper, as shown in Fig. 23. The plate 396 is then swung toward the partially folded ends until the lower projections 39? engage the lower flap on the partially folded wrapper and the upper projections contact the end closure between the partially folded wrapper and also the portions of the wrapper against the end closure. However, the plate 4!]! contacts the upper flap and no adhesive is applied thereto. When the plate 396 again swings away from the plates 398, 399, to the position of Fig. 23, the partially folded wrapper has adhesive applied thereto as in the manner shown in Fig. 36, and then the forming horn moves to station No. l to complete the folding of the wrapper.

The mechanism for completing the folding is shown in Figs. 1, 12 and 26, wherein the numeral 4H] designates supports connected to the frame 9 between which is journaled the shaft 293 carrying the drum 292 to the surface of which is secured a segmental brush carrier M3 having tufts of bristles or hair. The shaft 293 is keyed to a gear 4I4 meshing with the gear 415 on a shaft 4| I. The shaft 4H is keyed to a sprocket wheel 4l6 over which is trained the chain 4H, which (see Fig. 2) is also trained over a sprocket wheel M8 on the shaft 45'. Obviously, rotation of the shaft M! will rotate the gears 4H: and 4M and rotate the drum and brushes in the directio'n indicated by the arrow in Fig. 26. The forming horn stops at station No. I immediately in front of the drum 292 and beneath a plate 419 rotatably mounted on a shaft 420 supported above the frame 9. A lever All is connected to the plate 419 at one of its ends, and its other end is provided with a cam face 422 which contacts a lug 423 on the drum 292. At the front end of the plate 4L9 there is a depending finger 424 which is disposed above the upper unglued flap when the forming horn stops at station No. I, at which time the bristles are in the position shown in Fig. 26. When the gears M5, M4 rotate shaft 293 and drum 292, the projection 423 moves across the cam face 422 lowering the lever 42I and turning the plate 419 on shaft 420, whereby the finger 424 presses the unpasted flap down against glue spots on the end closure and portions of the wrapper thereagainst, after which the brushes raise the lower flap and wipe against'it completing the folding and pasting of the end of the container.

The container after leaving station No. I is in the condition shown in Figs. 37 and 38, and there is no suction on in the forming horn. When the forming horn arrives at station No. 8 from station No. I, the passages 29 in the turret and forming horn will register with a passage 426 in the support l8. The passage 426 communicates with a conduit 42'! leading to a source of air under pressure. When the passages 426 and 29 are in communication, a blast of air will come from the conduit 42! into the passages 28 in the forming horn and blow the container across table 428 on to a continuous belt 429. The belt is trained over pulley 430 on a shaft 43!.
